Summary

This observational study aims to measure how common obstructive sleep apnea (OSA) is in community populations, patients with conditions like hypertension or diabetes, and special groups in China. Participants will fill out a screening questionnaire, and some will undergo sleep monitoring to confirm the diagnosis. The goal is to evaluate the accuracy of different screening tools for identifying OSA across these populations.
